Stator coupling

Abstract

A stator coupling for the torsionally rigid connection of two components allows radial and axial relative movements within tolerance limits has a base surface ( 10 ) with first ( 18.1, 18.2 ) and second ( 28 ) lugs. The second lugs ( 28 ) are positioned at the straight-line edges between the assembly points ( 26, 42 ). Bent edges ( 30, 32 ) parallel to one respective edge are bent away at least twice, so that a flange ( 34.1, 34.2, 34.3, 34.4 ) surface-parallel to the base surface ( 10 ) is formed. Two second lugs, are positioned at edges following one another in the peripheral direction, and overlap with mutually facing ends of their flanges and these ends each together form one of a set of second assembly points ( 42.1, 42.2 ).
